[PATCH v23 1/3] dt-bindings: clock: npcm845: Add reference 25m clock property

[Tomer Maimon]

The NPCM8XX clock driver uses a 25Mhz external clock, therefore adding
clock property.

The new required clock property does not break the NPCM8XX clock ABI
since the NPCM8XX clock driver hasn't merged yet to the Linux vanilla.
